Leaving that for another day ... > Why did you post this? See patch 2/5: The 2835 has two SD controllers: The Arasan SDHCI controller that we currently use, and a custom SD controller.

On the rpi3 you can even use both in parallel, with the sdcard handled via custom sd controller and the wifi handled by sdhci-iproc. cheers, Gerd
